CANE-GUN BARREL.

SPECIFICATION forming part of Letters Patent No. 380,975, dated April 1.0, 1888.

Application filed August 29, 1887. Serial No. 248.149. (No model.)

T a/ZZ whom it may con/cern:-

Be it known that l, EDWARD DAvIs BEAN, of Arlington, in the county of Middlesex and State of Massachusetts, have invented lcertain new and useful Improvements in Cane-Gun Barrels, of which the following is a specifica tion.

This invention has for its object to provide a gun-barrel which shall be sufficiently light Io to adapt it for use in a cane-gun, and at the same time sufficiently stiff and inflexible; and

to this end my invention consists in a gun-barrel composed of a light inner tube of metal constituting the barrel proper, a tube of wood or other light non-metallic material inclosing the inner tube, and an inclosing-tube of leatheroid or equivalent brous material closely fitting and inolosing the wooden tube, the Whole constituting a composite tube so combining the qualities of lightness, stiffness, and strength as to make it'particularly desirable as the barrel of a cane-gun.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a longitudinal section of my improved gunbarrel. Fig. 2 represents a section on line x w, Fig- 1L.

The same letters of reference indicate the same parts in both figures.

In carrying out my invention I take a comparatively light tube, a, of steel or other suitable metal, the inner surface of which may be finished like the bore of an ordinary gun or rifle barrel. Said tube is externally threaded 35 at its ends, sothat the stock of the gun can be screwed upon one end and a tip or ferrule, b, upon the other end; Before the tip or ferrule is applied I drive upon the steel tube a an intermediate tube, e, of any suitable light and 4o strong` wood or other non-metallic material. Said wooden tube is formed to t very closely on the steel tube, considerable force being required to drive it to place on the latter. The

external surface of the wooden tubeis preferably tapered, as shown, its larger end being nearest the stock of the gun. l

A iiange, c, is placed upon the steel tube a i at one end of the wooden tube and bears against the latter. The tip or ferrule b is screwed upon 5o the opposite end of the steel tube and bears against the opposite end of the wooden tube,

as shown in Fig. l. I then apply to the outer surface of the wooden tube asheath or tube,

g, of leatheroid, the same being applied when it is in a soft and pliable state caused by soak- ,5 ing it in water. The leatheroid tube in drying shrinks slightly, and is thereby caused to adhere very closely to the Ywooden tube, the size of the leatheroid tube being such that when it is in a softened condition it will be just enough larger than the wooden tube-to enable it to beforced onto the latter without undue resistance. l

I use that variety of leatheroid which when dry becomes very hard and is susceptible of a polish. After the leatheroid tube has dried and shrunk firmly upon the wooden tube its outer surface may be polished to impart a desirable finish to the gun-barrel. A

The leatheroid casing is preferably extended, as shown in Fig. l, so that it covers the periphery of the collar c.

The gun-barrel thus constructed is much lighter than a solid metal barrel of equal external diameter, and is sufficiently strong and stiff to meet all the requirements of a cane-gun barrel.

The leatheroid casing being water-proof and tightly contracted upon the wooden tube protects the latter from moisture.

The wooden tube e and leatheroid casing g shrunk thereon constitute a light and stiff casing for the steel tube, preventing the latter from being indented and bent and from being ruptured by the explosion of the cartridge.

I prefer leatheroid as the material forthe outer casing, because it is tough, rigid, susceptible of a polish, and capable of contracting from a water-softened condition, so that it will firmly grasp the wooden tube.

The lcatheroid tube may be formed on the wooden tube, if preferred, instead of being formed separately and afterward applied to the wooden tube.

It is obvious that the intermediate tube, e, may be made of pulp or some other equivalent material, instead of natural wood.

I claim-- 1. Theimproved gun-barrel composed of the inner metal tube, the intermediate tube inclosroo n ing the metal tube, and the external Waterund tip, und the external ease of leutheroid proof binding' Case or tube covering the ini'ershrunk upon the Wooden tube and extended mediate tube. as set forth. beyond the end of the latter upon the collar, i5
